different behaviour between 4.0.2.3 and 4.1.0

[getagrip]

I just realized that any variables that are not substituted in my vlib-templates are now (4.1.0) printed in html with their full syntax so lets say I have

username:<br/>
<input type="text" name="username" value="{tmpl_var name=username}/>

and I do NOT substitute username with a value in my controller then I get the following output in my browser:

username:
{tmpl_var name=username}

This was NOT the case in the prior version (4.0.2.3). It would print NOTHING which was very convenient.
Now I have to substitute all insiginificant variables with an empty value so nothing gets printed which complicates things a lot.
Was this intended?

All your posts will be closed until you get a username, which is not violating against the rules.

"You have to use a part of your REAL NAME (e.g. John Doe = "JohnD" or "john.doe") for registration. You have to use a valid mail adress, which is similar to your account name ("[email protected]"). If you do not follow theses rules your account will be DELETED."

"getagrip" is not a real name.
